Having a blocked ear (or sometimes, even more annoyingly, blocked ears) can be a serious inconvenience, and at times, a health risk. Blocked ears can muffle and distort sounds, reducing your capacity to hear your surroundings. Having blocked ears is not only irritating, but usually comes with other symptoms such as ear pain, itchiness, or dizziness.
When a blockage occurs, especially if it seems out of the blue, you may wonder why your ear is blocked. There are many causes of a blocked ear; surprisingly, it’s not always the case of ear wax buildup. Although there are many reasons an ear can be blocked, we highlight the five most common reasons your ears are blocked.
Opening the eustachian tube allows for the release of pressure. This cures the ‘ear block’. If you’re experiencing an infection, antibiotics are usually prescribed to help fight off the infection. Often, for sinus congestion resulting from colds and flues, nasal sprays are also prescribed. However, if the blockage does not clear, there is a dysfunction in the tube. This could cause further complications leading to infection if not treated (though this is rare). If you’re experiencing frequent ear blocks that may be attributed to ETD, it’s a good idea to get your ears checked out by a qualified hearing health specialist.
The middle ear is a sensitive region of the overall ear. The middle ear is located between the eardrum and the oval window and is responsible for transmitting sound from outer ear to inner ear. This is where three incredibly small and sensitive bones called the hammer (malleus), the anvil (incus) and the stirrup (stapes) transmit vibrations into sounds waves that travel into the inner ear.
Sometime a sinus congestion (resulting from illnesses, sinus infections, and allergies) can cause the eustachian tubes to block, leading to fluid buildup in the middle ear and inflammation. Further, a bacterial sinus infection can spread to the middle ear causing swelling, fluid buildup, and infection. This is a condition known as otitis media and is often associated with ear pain and pressure. Most of the time otitis media will clear up on its own; however, at times antibiotics are prescribed. Treatment is delivered based on the underlying issue – whether it be viral or bacterial.

Earwax is a naturally occurring substance which protects the ears from water, bacteria, fungi, and other elements. It helps the ears stay lubricated and clean; however, sometimes excess earwax builds up which causes problems. This is referred to as Excessive Earwax or Impacted Cerumen
Typically, earwax that is produced by the ear is pushed towards the outer part of the ear where it is washed away or falls out; however, people with excess ear wax may find that too much wax in the ear blocks their hearing. Further, as earwax builds up over time, it may harden and become difficult to wash away; this also makes ears more susceptible to blockages. Earwax blockage is not only annoying, but can lead to other health problems. According to Harvard Health, ear canals that become plugged up with earwax can cause earaches, infections, and other problems.
On top of conductive hearing loss, other symptoms of excessive earwax include pain in the ear, itchiness, or dizziness. For treatment of impacted wax, it’s important to talk to a hearing or ear health specialist. A specialist can remove the wax safely and recommend products and wax-removal methods (more on safe, at-home earwax removal below!).
Otitis Externa, or swimmer’s ear, is the inflammation or infection of the canal between the eardrum and outer ear. This is often triggered by exposure to water or over-cleaning the ear. Apart from reduced hearing, a person with this condition may also experience pain, itchiness, pus in the ear canal, and buzzing or humming noises from inside the ear canal. Otitis externa is often treated after first establishing whether the infection is fungal or bacterial. Following this, antibiotics or antifungal medication is prescribed and the ear is cleaned out.
If the pressure in your ear is different from the pressure of the air outside your body for extended periods of time, severe damage to your eardrum can result. This type of damage is called barotrauma and is often experienced by those who scuba dive, fly regularly, and drive or hike at high altitudes. Barotrauma causes ear pain, dizziness, and a feeling of pressure in the ears. Severe barotrauma can cause eardrum rupture, hearing loss, and nosebleeds.
With this condition, it’s best to treat the discomfort before it escalates and causes damage to the eardrum. On flights, it’s a good idea to chew gum to let your eustachian tube open. When scuba diving, come up to the surface when you first notice discomfort to let your ears equalise. In most cases, symptoms will resolve on their own; however, if serious damage is caused, corrective surgery might be needed.
Ear wax is a natural, healthy and needed bodily fluid. In fact, earwax has been shown to have antibacterial and antifungal properties, according to Harvard Health. Overall, earwax should only be removed if it is causing a blockage. To do so, it is recommended individuals use droplets of hydrogen peroxide, baby oil, mineral oil, or glycerin. These dissolves and softens the wax and allows it to drain out along with the excess liquid. It is recommended that you do not use a cotton swab, as this can push earwax deeper into the ear and cause more blockage, and it can cause damage to the ear canal or eardrum.
Though blocked ears can be quite uncomfortable, distracting, and inconvenient, they usually go away on their own or with the appropriate action by your GP. To prevent blockages from forming, always use safe practices when cleaning your ears, like the method outlined above.
